6weeks .neg.
8 weeks . Neg.
10weeks.neg.

Response from Ms. Southall

Hi
The testing guidelines for HIV are to be initially tested at 3 weeks post exposure and then again at 90 days. As long as there are no other exposures happened during this time frame than the results are conclusive.
Having your test at 18 weeks come back negative and as long as there have been no other exposures during this time you can consider the test conclusive.
